Try starting Firefox from the command line to see info on what's going on during startup. In particular, you might want to use firefox -safe-mode to see if you get a fast startup that way. If so, then it's probably an add-on causing the delay.

Incidentally, since someone else has suggested that a slow startup is somehow normal for Firefox, let me point out that Firefox is known to have a fast startup on 11.10. At least, according to this Tom's Hardware testing, it beat Chrome and Opera when loading one tab. Personally, I find the startup very swift on Precise beta2.

I saw some problems (not error, but notice or warning) about Firefox's theme engine when start on 11.10 .

But I don't think that this makes it slow down too much.

Chromium is faster than Firefox (I am a fun of Firefox by the way). If you are talking about this, it seems to be normal. Try to remove unused add-ons, that may help you make it a little faster (depending to the number of add-ons)
